Not at all, it's an often used marketing technique, generally by an underdog (even if only a slight underdog) to try and pull in customers who would actually like their product better if they had tried it.
The most famous example would be The Pepsi Challenge [1], but it happens all the time, for example AMD have done it at a few events comparing an AMD machine to a similar spec/price Intel build.
There is nothing "weird" about blind "taste" tests. It's a good way to attempt to filter out at least a little bias, and here you have two competing products that do the same thing (unless your baseline assumption is that no one could ever compete with the current leader).
